Just when I first read Buchanan’s The Limits of Liberty (1975) 30 years ago, I find the following intriguing or troubling:

In the model incorporated here … I allow quite explicitly for personal inequality in the natural equilibrium, the anarchistic base from which primal disarmament contracts are conceptually negotiated. … [T]he establishment of positive claims to stocks of goods or endowments may not be possible until and unless some unilateral transfers are made. This potential for transfer allows us to introduce an additional dimension of adjustment which may possibly facilitate the reaching of agreement among parties in contract. …
[C]ertain “exchanges” of resources endowments of goods and behavioral constraints may be necessary before clearly acknowledged ownership imputations are possible. (pp. 92-3)
